Abstract
The present work evaluates a multilayer structure based on epoxy resin for stealth technology. The structure consists of two absorber layers with nanoferrite and a resistive layer between them containing polyaniline (PANI) with and without carbon nanotube (CNT). The best reflection loss result multilayer structure analyzed was Ni-PANICNT-Fe with RL = –22dB at 11,9 GHz, justified by higher conductivity loss due to the CNT in PANI epoxy composite.
Highlights
In recent years, radar absorbing materials (RAM) have attracted considerable attention due to their potential use in stealth technology, military radar, satellite and electronic equipment applications
It was observed that those properties for PANICNT are higher in relation to PANI, which may be justified by the presence of carbon nanotube (CNT) that promotes more interfacial polarizations than only PANI
It was found that the order of the absorber layers slightly increases the value of RL, depending on the resistive layer between them; for example, when the resistive layer is PANI and Fe is in contact with air, RL = –16 (Ea = 97%) at 12.4 GHz, and when the resistive layer is PANICNT and Ni in contact with air, a RL = –22 dB (Ea = 99.1%) at 11.9 GHz was obtained, emphasizing that the multilayer structure is a broadband xx4/0xx Silva TI; Soares KP; Pereira IM; Calheiros LF; Soares BG
Summary
Radar absorbing materials (RAM) have attracted considerable attention due to their potential use in stealth technology, military radar, satellite and electronic equipment applications. A ratio of 80/20 wt %, Epoxy/PANI with and without the presence of CNT (PANICNT) was established.
